Resolved Structure and Orbital Motion of a Localized 1 au-scale Dust Accumulation in the Protoplanetary Disk around TW Hya

Takashi Tsukagoshi, Takayuki Muto, Hideko Nomura +6

We present the results of high-resolution (~au) Atacama Large Millimeter/submillimeter Array (ALMA) observations of the TW~Hya protoplanetary disk in the Band 6 dust continu…

Time-variable Scattered Light in Herbig Disks Observed with Subaru/SCExAO

Camryn Mullin, Miles Lucas, Ruobing Dong +12

Using the Subaru Coronagraphic Extreme Adaptive Optics (SCExAO) instrument, we present near-infrared K-band polarimetric imaging of nine Herbig stars selected from a volume-limited…

ALMA 873 m Polarization Observations of the PDS~70 Disk

Hauyu Baobab Liu, Kiyoaki Doi, Simon Casassus +4

At a 112.4 pc distance, the PDS70 protoplanetary disk is a rare case that has been confirmed to host two accreting planets. This makes it the most important laboratory for studying…

VLT/MUSE Detection of the AB Aurigae b Protoplanet with Spectroscopy

Thayne Currie, Jun Hashimoto, Yuhiko Aoyama +6

We analyze high-contrast, medium-spectral-resolution observations of the star AB Aurigae using the Very Large Telescope's Multi Unit Spectroscopic Explorer (MUSE). In m…

JVLA Measurement of Grain Size in the Compact Dust Ring around Class I Protostar WL 17

Jun Hashimoto, Hauyu Baobab Liu, Ruobing Dong +2

The maximum grain size in protoplanetary disks is a critical parameter for planet formation, as the efficiency of mechanisms like streaming instability and pebble accretion depend…

Mapping the merging zone of late infall in the AB Aur planet-forming system

Jessica Speedie, Ruobing Dong, Richard Teague +10

Late infall events challenge the traditional view that planet formation occurs without external influence. Here we present deep ALMA CO and SO observ…

Predictions of Dust Continuum Emission from a Potential Circumplanetary Disk: A Case Study of the Planet Candidate AB Aurigae b

Yuhito Shibaike, Jun Hashimoto, Ruobing Dong +3

Gas accreting planets embedded in protoplanetary disks are expected to show dust thermal emission from their circumplanetary disks (CPDs). However, a recently reported gas accretin…

Gravitational instability in a planet-forming disk

Jessica Speedie, Ruobing Dong, Cassandra Hall +7

The canonical theory for planet formation in circumstellar disks proposes that planets are grown from initially much smaller seeds. The long-considered alternative theory proposes…

First JVLA Radio Observation on PDS70

Hauyu Baobab Liu, Simon Casassus, Ruobing Dong +3

PDS~70 is a protoplanetary system that hosts two actively accreting gas giants, namely PDS~70b and PDS~70c. The system has a 60--100 au dusty ring that has been resolved by A…

Forming localized dust concentrations in a dust ring: DM Tau case study

Hauyu Baobab Liu, Takayuki Muto, Mihoko Konishi +8

The previous, high angular resolution 225 GHz (1.3 mm) continuum observations on the transitional disk DM Tau have resolved an outer ring at 20-120 au radii that is weakly az…

Shadowing in the protoplanetary disk of ZZ Tau IRS with HST

Jun Hashimoto, Ruobing Dong, Takayuki Muto +2

An inner component misaligned from an outer component in a protoplanetary disk can result in the former casting shadows on the latter. We present a new instance of shadowing on the…

High-Resolution Near-Infrared Polarimetry of a Circumstellar Disk around UX Tau A

Ryoko Tanii, Yoichi Itoh, Tomoyuki Kudo +65

We present H-band polarimetric imagery of UX Tau A taken with HiCIAO/AO188 on the Subaru Telescope. UX Tau A has been classified as a pre-transitional disk object, with a gap struc…

Imaging of a Transitional Disk Gap in Reflected Light: Indications of Planet Formation Around the Young Solar Analog LkCa 15

C. Thalmann, C. A. Grady, M. Goto +47

We present H- and Ks-band imaging data resolving the gap in the transitional disk around LkCa 15, revealing the surrounding nebulosity. We detect sharp elliptical contours delimiti…
